Measurement Unit Symbol (D=M/V) Bell Work: 9/9/13 Grab a flash card and fold it accordion style so that it has 3 sections Copy this chart below into the separate sections *My example is below* Measurement Unit Symbol Mass (not weight) kilogram kg Length meter m Temperature Kelvin K Time Second s Volume Cubic centimeters OR Liters cm³ OR L Density grams per cubic centimeter OR grams per Liter g/cm³ OR g/L (D=M/V)

The metric system

SI/Metric The international system of units (SI) is a version of the metric system that modern scientists use. WE DO NOT USE THE STANDARD SYSTEM IN SCIENCE! http://chartsbin.com/view/d12

Measurement Unit Symbol Mass (not weight) kilogram kg Length meter m Temperature Kelvin K Time Second s Volume Cubic centimeters OR Liters cm³ OR L Density grams per cubic centimeter OR grams per Liter g/cm³ OR g/L

Length Length is measured in meters Kilometers 1000 Hectometers 100 Dekameters 10 Meters Decimeters 0.1 Centimeters 0.01 Millimeters 0.001

Mass Mass is measured in grams Kilograms 1000 Hectograms 100 Dekagrams 10 Grams Decigrams 0.1 Centigrams 0.01 Milligrams 0.001

Volume Volume is measured in Liters OR cm³ Kiloliters 1000 Hectoliters 100 Dekaliters 10 Liters Deciliters 0.1 Centiliters 0.01 Milliliters 0.001

Other SI Units Time is measured in seconds (milliseconds are also often used) Weight is measured in Newtons Temperature is measured in Celsius or Kelvin

1 kilometer = 10 hectometers = 100 dekameters = Since each step is ten times or one-tenth as much as the step on either side, we have: 1 kilometer = 10 hectometers = 100 dekameters = 1000 meters = 10 000 decimeters = 100 000 centimeters = 1 000 000 millimeters Or: 1 milliliter = 0.1 centiliters = 0.01 deciliters = 0.001 liters = 0.000 1 dekaliters = 0.000 01 hectoliters = 0.000 001 kiloliters

Density mass ÷ volume = density grams ÷ cm³ = g/ cm³ OR grams ÷ Liters = g/ L What makes me float? Hmmm . . . Which ones will float and which ones will sink?

*No students were harmed in the making of this word problem* there was a really talkative student. Mrs. Supan’s evil twin taught this student and she knew that the talkative student needed to be taught a lesson. She found a roll of duct tape that measured 44.5 cm. The talkative student’s mouth measured 150.4 mm. Mrs. Supan’s evil twin wondered if she had enough tape to cover . . . *No students were harmed in the making of this word problem*
